WILHELM BRASE, OF BERLIN, GERMANY.

snwmo Macrame.

Application filed October 12, 1923. Serial No. 888,250.

To all whom it may concern:

Be it known that I, WILHELM BRASE, a citizen of the German Republic, and resident of Berlin, Germany, have invented new and useful Improvements in Sewing Machines, of which the following is a specification.

My invention relates to a machine in which cloth or other suitable material may be provided with embroideries, festoon stitches, hemstitch or the like, and which work is done automatically under the control of a jacquard device. With my invention, I produce the backward and forward stitches by shifting the fabric, and the side stitches by moving the needle and the parts cooperating therewith. By this arrangement, the fabric is prevented from lateral movements and is thus properly guided, which is necessary, particularly when hemstitch or edge seams are produced. Owing to the use of only four kinds of stitches and combinations thereof, my jacquard device needs only four adjustments, and the cam chain or perforated band actuating said jacquard device needs only four rows of cams or perforations. The cam chain consists of a number of plates, preferably of sheet metal, formed with ribs in form of cams, according to the pattern to be produced, the plates being fastened to each other by means of hooks or the like. For

the purpose of feeding the fabric in a certain direction, I preferably use two fabric feeders, although a single feeder may be used, of suitable construction, one of said feeders acting in forward direction and the other in backward d rection.

Further I provide two presser bars, each away; Fig. 2 is a plan view thereof; Fig. 3 is a vertical cr0ss-section of the machine showing the parts actuatin the fabric feeders; Fig. 4 is a vertical section on-line A-A of- Fig.1; Fi 5 is a vertical sectionon line B--B of .ig. 1; Fig. 5 is an enlarged cross section of the machine showing the ad- ]ustment lever; Fig. 6 is a front view of the machine; Fig. 6 is a side elevation of one of the fabric feeders; Fig. 7 is a vertical section on line DD of Fig. 1; Fig. 8 is a longitudinal section on line G-O of Fi .6; Fig. 9 shows a link of a pattern chain;' l ig. 10 is a longitudinal section on line A-A of Fig. 9; Fig. 11 is, a side elevation of the chain carrying drum and of a part of the chain; Fig. 12 is a pers ective view of a modified attern chain; i 13 is a front view of t e lower art of t e presser rods; Fig. 14.5 is a side ei vation thereof; Fi 15 is a plan view thereof Fig. 16 is a ront view of a modifiedpresser foot; and Fig. 17

is a plan view thereof. v

WVith reference to Figs. 1-17, the frame of the machine consists of the base plate 1 and the arm 2, the free end of which forms a head. Within the arm 2, bears the shaft 3 to the front end of which is attached the crank pin 4 (Fig. 8) adapted to reciprocate the needle bar 5 (Figs. 1 and 6) in: vertical direction and. to operate a lever'7, one end 8 of which is pivoted in the head of the machine, and from the other end 9 of which is suspended a frame 10 (Figs. 1 and 6) from which the upper end of the needle bar 5 is suspended to be laterally slidable. By virtue of this arran ment, the needle bar cafi move laterally, w 'le recipmcated vertica y.

The crank pin 4, at the same time, actuates the thread-supplying mechanism 11, 12, which is of we l-known construction and has the purpose of adapting, in well-known manthe sewing operation. The sewmg thread is taken froma bobbin 13' supported on a pin 13 carried by the arm 2. From this bobbin the thread passes over the wellknown brake mechanism 14 and through an eye 15 of an arm 11 (Fig. 6) of said thread-sup.-

. plying mechanism. Then after passing through an eye. provided in the end of an at as uniform a length as possible.

and the upper end of said bar is formed with an eye 19 slidably engaging a rod 20 carried.

by the frame 10 (Fig. 1).

The front of the head of the arm 2 is closed by a cover plate 21, to which the brake discs 14 are fastened. The threadsupplying lever 11 projects through a slit 22 (Figs. 6 and 8) provided in this cover plate 21. From the bobbin 13 the sewing thread passes through an eye 23 in an ear of the plate 21. In vertical direction the needle bar 5 is guided within a bore of the front portion 25 of a rectangular frame, the rear end of which is pivotally connected by means of arms 26, 27 to the front portion of a frame 28, the rear part of which is pivoted at 29, 30 (Fig. 8) in the arm 2.

The front portion of the frame 28 is provided with a member 31 (Fig. 1) to which is connected a horizontal actuating rod 32. The lower end of the portion 25 is guided with a slit of a fork 25 fastened to the under side of the head of the machine. The rear end of the shaft 3 carries a strap disc 33. Mounted on said shaft 3, are further a cam disc 34, a crank 35, a cam disc 36, a cam disc 37 and alongside the latter a cog wheel 38 with which meshes a larger cog wheel 39 to which is fixed a smaller cog wheel 40 (Figs. 1 and 3). Both wheels 39, 4O rotate on a pin 41 fixed in a bracket 43 (Fig. 2) of the arm 2. The bracket 43 carries also a second pin 44 on which is rotatively mounted a cog wheel 45 meshing with the cog wheel 40, and to which is fastened the chain drum 46, so that the latter can be turned through the medium of shaft 3. The drum is of polygonal shape, so that a number of planes are formed on which the links of the pattern chain may bear. At every revolution of the shaft 3, a plane of the drum 46 is turned in opposite direction to that of the actuating mechanism hereinafter to be described. The stroke of the motion of the cog wheels 38, 39, 40 and 45 is to be arranged accordingly.

At the under side of the base plate 1, are arranged the cloth feeders and the shuttle mechanism.

The casing 47 (Fig. 8) for the oscillating shuttle of well-known construction is fastened to the front end of a tube or sleeve 48 slidably supported in bores of arms 49, 5O projecting downwardly from the under face of the base plate 1, The shuttle shaft 51 is borne within the sleeve 48 and carries at its rear end a crank'52 having a crank pin 53. Above and parallel to said sleeve 48 and the shuttle shaft 51, is'arranged a fixed rod 54 on which is rotatably mounted, by means of a hub 55, a forked lever 56 (Figs, 4 and 8). The pin 53 of the crank 52 engages the slit of said forked lever 56. Connected to the latter with one end is-further a forked lever '57, the other end of which is fulcrumed in the plate lat 57 (Fig. 4). Pivoted to said lever 57 is a connecting rod 58, the other end of which is connected to the crank 35 of the shaft 3 (Fig. 1). -()n turning the latter, 1118 connecting rod 58 is reciprocated in vertical direction. The pin 53 of the crank 52 thereby receives at the same time oscillating movements, which by means of the shuttle shaft 51 are transmitted to the shuttle. At the same time, the shuttle casingand the shuttle with its cooperating parts are able to move in longitudinal direction of the machine, as the crank pin 53 is allowed to slide within the slit of the lever 56. Mounted between the arm 2 and the plate 1, is a vertical rock shaft 59 (Figs. '7 and 8), from the upper end of which projects laterally an arm 60, to the end of which is connected the rod 32 (Fig. 1). Projecting from the lower end of said rock shaft 59, is a similar arm 61, the end of which is connected by means of a connecting rod 62 to the sleeve 48 carrying the shuttle casing 47. In this manner, the needle 17 with its cooperating parts and the shuttle with its parts are so connected to each other that both are caused to always move in unison in longitudinal direction of the machine.

These movements preferably are effected through the following mechanism:

Cooperating with the cam disc 37 of the shaft 3, is a fork 63 (Figs. 5 and 8) formed on the upper end of a rod 64. Immediately below said fork, the rod is provided with a lateral pin 65 adapted to engage a groove 66 of a rail 66, which by means of a pin 67 rotatively bears in the wall of the arm 2 (Figs. 5 and 8). Projecting from said rail 66 is an adjustment lever 68 (Figs. 5, 5a) which is formed with a lock pin 68 coopcrating with notches or holes 2 provided on a part projecting laterally from the arm 2. 'By slightly bending the lever 68 laterally its lockpin 68 becomes disengaged from a notch 2 and by swinging the l ver around the axis of the point 67, the groove and its rails 66 are capable of being adjusted into a more or less slanting position, so that the stroke of the Vertical movements of the rod 64, when reciprocated by the rotation of the shaft 3, according to the position of said rail, will be made larger or smaller. The lower end of the rod 64 is joined by a ball and socket bearing 69 to an arm 70 projecting laterally from. a shaft 71 arranged CPI transversely of the machine Fig.8). From 1, projects an.

the front end of this shaft upright arm 72 to the free end of-which is connected an arm 73 1). ing from the upper endo the latter, is a knife edge 74. From the shaft 71 projects laterally an arm 75, the free end 0 which engages the slit of a fork provided in an arm (6 of equal le h. This arm is arranged on a shaft 77 borne in the machine parallel to the shaft 71. The shaft 77 has an upright arm 78 of a length equal to that of the arm 72. Tothe end of the arm 78, is pivoted a member 79 rovided at its free end with an upright knife edge 80. When the shaft 3 is rotated, the arm oscillates -vertically and correspondingly the arm .72

oscillates in horizontal direction, while the arm 78 performs equal movements but in opposite direction.

To the right-hand end of the connecting rod 32 is pivoted a member 81, the free end of which is capable of moving up and down and the lower face of which is formed with sharp teeth. By the pressure of a spring actuated bolt' 82, the member 81 is kept in engagement with a stationary knife edge 83 (Fig. l) fixed to the frame of themachine. Thereby the needle and shuttle are normally prevented from moving in longitudinal direction of the machine. The knife edges 74 and are capable of moving below the teeth of the member 81:

When now the needle and its cooperating parts are to be reciprocated laterally stepby step to produce a right-hand or left-hand stitch, then correspondingly either the knife edge 74 or the knife edge 80 must be temporarily raised. In order to produce a left: hand stitch, the knife edge 74 must be raised into engagement with the member 81, raising thereby the latter from the stationary knife edge 83. The knife edge 74 then moves to the left. At the completion of this movement, the knife edge 74 is lowered, so that the member 81 again bears on the stationary knife edge 83.

The operations hereinbefore described are indirectly controlled by a jacquard device to be hereinafter described.

In order to feed the fabric to be embroidered in sewing direction, I preferably provide two independently acting feeders, (Fig. 6). Each of said feeders comprises a plate 84 toothed on its upper face and the teeth of which project through a row of slits arranged in the stitch plate 85. Said teeth engage the fabric to be treated, and at the same time press the same against the press er foot or feet. Each plate 84 is attached to the free end of a member 87. The other end of one of these members is pivoted to two arms '88 projecting from a shaft mounted in the base plate 1 parallel to the shuttle mechanism. The shaft 30, at its Proj ect-' ments, whereby tending arm 99 and the shaft 96. is

right end, is providedwith an arm 91 .(Fig.';,

4) extending towards the middle of the plate -1 and to theend of which is'oonnected a rod 92. I The upper freeendof'said rod 9 is formedto a fork 93, and the same oooperates with the cam'disc 34 of'the shaft the shaft 3 the fork oscil- Below the fork extends a in 93 enga ing. his latterfiszin' rail 66. By adjusting this rai 94-into the desired slanting position by means of an ad ust1ng lever 95, the rod 92 receives corresponding vertical reciprocatory move and the shaft 90, the corresponding feed member 87 is rediprocated. A shaft 96' (Fig. 6) parallel to shaft 90 su ported in the plate 1 is h rovided with t e upright arms 97 98 (Figs. 1 and 6) carryingthe second feed member 87. The shaft 90 is further provided with a downwardly exvided with an upright arm 100. Both arms are connected. with one anotherby'means of a rod 101,;so that the rotary movements of the'shaft 90'are transmitted to the shaft 96 in opposite directions. Consequently both feed members move to andfro in opposite directions". When'at rest, the teeth of said feedmembers are about level with the surface of the stitch plate.

In order-to feed the fabric to be treated forward or backward by said feed members 87, it is necessary to raise, one or the other feed member. When raised, the feed member presses the fabric against the presser foot or feet 86, which is or are thereby somewhat lifted. When. the feed member 'is again lowered the presser foot presses the fabric against the stitch plate, and the fabric is thus prevented from moving.

The lifting of the feed member 87 in proper time is indirectly caused by my jacquard device lows:

A pattern chain (Figs. 9-12) is guided by a drum 46. Thecham is composed of a number of plates 102 preferably connected by means of the arm-91' preferably constructed as folperforations 104 in thel.

bination of plates of the different kinds, pattern chains can be formed for the automatic production of embroideries, festoon stitches or hemstitches of the greatest variety of design. The plates may be made fiat, as in Figs. 9-11 or be arched as in Fig. 12. For the latter kind, the drum 46 is made cylindrical.

Within the arm 2, I provide four pendula 106 (Fig. 3), each of which is provided at its lower end with a horizontal arm or bar 107, the outer end of which carries a roller 108. By means of springs 109,, these rollers are forced against the pattern'chain guided by the drum 46. The other end of each bar 107 cooperates with one of four upright fingers 110. Each finger 110 is pivoted with its lower end to a lever 111. All four levers 1.11 are rotatably mounted on a shaft 112 supported in the frame of the machine. For the purpose of adjustment, each lever 111 has a finger 113 bearing against a set screw 114, four of which are rovided at suitable places in the frame of t e machine.

The cam disc 36 on the shaft 3 is mounted above the arms 110 and cooperates with a fork 115 of a lever 116 fulcrumed at 117 to the frame of the machine. On its lower face, said fork has a projecting ledge 118.

\Vhen the shaft 3 is revolved, the fork 115 receives oscillatory motion, so that when its projecting edge 118 is lowered, it engages one of the fingers 110, which by corresponding cams of the pattern chain have been brought into its range, depressing said finger.

From the hubs of two of the levers 111 also project arms 119 provided at their free ends with rollers 120, which engage slits in the arms 73 and 79, said arms 119 being drawn downward by springs 121 (Figs. 1 and 5). When while lowered, the ledge 118 of the fork 115 engages one of the fingers 110, the corresponding lever 111 is moved, and its arm 119 pushes the knife edge 74 or 80 against the rack of the member 81. The same thereby is lifted from the stationary knife edge 83 and now the needle 17 with its cooperating parts is shifted laterally under the influence of the cam disc 37.

From the hubs of bothother arms 111 project arms 121 (Fig. 3), which by rods 122 are connected to arms 123 provided on shafts 124 parallel to shafts 90 and 96 and supported in the base plate 1 (Fig. 6). From the shafts 124, extend arms 125 towards the shuttle mechanism provided at their free ends with rollers 126 engaging slits in the members 87.

lVhen now one of the previously men tioned fingers 110, influenced by a corresponding cam of the pattern chain, is shifted into the range of the ledge 118 and is de pressed by the latter, the corresponding shaft 124 receives a rocking movement through the arms 111 and 121, the correspondmg rod 122 and the corresponding arm 123. Thereby the correspondin arm 125 lifts the corresponding member 8% by means of its roller 126. The feed member 84 thereby presses the fabric against the presser foot 86 and the latter, together with the fabric, is raised, and under the influence of the cam disc 34, the latter is fed one step. By presser springs 136 (Fig. 6) the feed members 87 are forced downward.

In my machine, I preferably provide two presser foot rods 127. Both are spring actuated, and they can be lifted independently by means of levers in well-known manner. Preferably to one of the two rods (Figs.

13-15) a foot 86 is adjustably fixed, while I the other rod 127 carries a foot 86, which can be laterally adjusted to be farther from or nearer the foot 86. To this end, the corresponding rod 127 has fixed to it a plate 131 grooved at its back, as at 131 (Fig. 14), and provided with a longitudinal slit 131 for the passage of a fastening screw 133 carrying a nut 132. The opposite faces of the plate 131 and of the upper part of the foot 86 are provided with fine teeth, as at 131, so that the foot will be securely held in position perpendicular to the surface of the stitch plate. The opposite edges of the feet 86, 86' are provided with notches or slits 134, 135 through which the embroidering needle is able to draw the thread from one foot to the other.

In case of using only one presser foot, or broad feet, I preferably construct said foot or feet 86 in form of a comb, as at 86", as shown by Figs. 16 and 17.
